Claims resulting from non-appropriated fund activities may be denied only by the TCU Norfolk. The denial will begin the six-month limitation on filing suit against the United States for claims filed under the FTCA. Denial of a claim shall be in writing and in accordance with subparts A and B of part 750 of this chapter, as appropriate. The TCU Norfolk should not deny claims that have initially been processed and negotiated by a non-appropriated fund activity, its insurer, or TPA, until the activity or its insurer has clearly stated in writing that it does not intend to pay the claim and has elected to defend the claim in court.
